Internal error logged from JDI Debug

I am trying to debug a server plugin, and I got the following exception:

org.eclipse.jdi.TimeoutException: Timeout occurred while waiting for packet 2743.

The steps I took to set up this debug session are:
1) Download JazzServer-06-RTC10-Maximal.launch
2) Modify it slightly to fix the org.apache.logging problems
3) Add my custom server plug-in to the configuration on the 'Bundles' page of the Debug Dialog
4) Run the launch from the Debug Dialog
5) Logon to the localhost server using ADMIN/ADMIN
6) Click on Project Areas

Has anyone seen this before and have a resolution?

Thanks,

Dave
